1. A near field communication (NFC) device, more particularly, to a device capable of near field communication by using ZigBee and Bluetooth communication modules, the NFC device at least comprising:

  • a ZigBee communication module, a Bluetooth communication module, a signal conversion/transmission circuit and a power supply circuit, wherein;

    the ZigBee communication module includes a master central processing unit (CPU) capable of processing N-Fi communication protocol, identifying and enabling ZigBee communication, and the master CPU is connected with a communication chip that can transmit or receive ZigBee-based information packets;

    the ZigBee communication module is equipped with a ZigBee memory that can temporarily store ZigBee-based information packets that have been processed, transmitted or received and delete these information packets after processing;

    the Bluetooth communication module includes a master Bluetooth CPU that can control processing of Bluetooth communication, and this master Bluetooth CPU is connected with a Bluetooth communication chip capable of sending or receiving Bluetooth-based information packets;

    in addition, the Bluetooth communication module is equipped with a Bluetooth memory that can temporarily store Bluetooth-based information packets processed, transmitted or received and delete these information packets after processing;

    the signal conversion/transmission circuit is used to process internal transmission of information packets inside the ZigBee and Bluetooth communication modules;

    and the power supply circuit is electrically connected between the ZigBee and Bluetooth communication modules, and is a power supply unit that can provide electricity to the Bluetooth and ZigBee communication modules as needed.
